Thanks <blush>

Well, there are always the standard approaches, e.g. PyEval_CallFunction(),
etc.

Well, it's an interesting idea, but I'm a bit unsure what you'd use this
for, or why it's better than e.g. writing a python file and telling python
to execute that. Maybe you have some more concrete ideas about how to use
this?
